I'm looking for a telephoto to compliment my D70's kit lens. I really like the kit lens, but at times I'm looking for the reach it just doesn't have.
I will be going overseas later this year and I would like to take my gear with me, so weight is a concern. I will be shooting scenic, people, wildlife, etc.
My budget is limited, so here are the ones I've been looking at.
Sigma 70-300mm f4-5.6 APO Macro Super II - $220
(What's the difference between the above lens and the Sigma 70-300mm f4-5.6 APO DG Macro Telephoto Zoom Lens?)
Nikon Zoom Telephoto AF Zoom Nikkor 70-300mm f/4.0-5.6D ED - $260
Nikon Zoom Telephoto AF Zoom Nikkor 70-300mm f/4-5.6G - $130
Does anyone have any experience with any of these lenses?
Also, what kind of circular polarizer filter should I be looking at? Some are out-right expensive. Am I OK with the less expensive ones?
